wjp: I think the word "Presumably" indicates that this is an educated guess...

After I read this a few times, I think [md5] means the following:
That if the gamedata sets the hotspot for a cursor to a value outside of the screen size, then the effect is to display a cursor, but ignore mouse click events, but there is no explicit code for this i.e. it is an implicit effect / abuse in the original interpreter.

Someone needs to look at the original interpreter disasm to see whether this guess is correct...
